Macro Analysis Would Like to Drop Half a Drop of Solution
By strong alkali (acid) titration strong acid (alkali), alkali (acid) titration mono-weak acid (alkali), precipitation titration and coordination titration to drop by half a drop, and settling the titration error specific terms, to illustrate the macro titration analysis would like to have drop half a drop of a solution. When strong alkali titrate strong acid or monobasic weak acid, there is no need to drop half a drop. As strong acid titrate strong alkali, there is must to drop half a drop as methyl orange for indicator. But phenolphthalein as indicator, there is doesn't need to drop half a drop. Strong alkali titrate monobasic weak acid, there is no need to drop half a drop. Eriochrome Black T for indicator titrate magnesium ion with EDTA, there is must to drop half a drop. Titration of zinc by EDTA, don't need to drop half a drop. Titration chloride ion with Moore method can not drop half a drop.
